Original application Ju 31,645, now Patent N April 2, 1948 England 2,593,357, dated April Great Britain 4 claims. (01. 299-438) a slot or slit-like outlet.

An object of the present invention is to control the'direction and the pressure or volume, or both, of the emergent stream along the said slit.

' to the present invention a nozzle for the ejection towards each end of the nozzle.

According to the present invention a nozzle having a slot or slit-like outlet for the ejection erably disposed within the nozzle to deflect the fluid discharged therefrom.

According to a further feature of the invento the longitudinal axis of the slit.

This fluid nozzle has a particular scope of utility in connection with washing machines for tex- The invention is further described with reference to the accompanying drawings which show by way of example an embodiment of the invention, and in which:

Fig. 1 is a sectional plan view of one form of nozzle embodying the present invention on the line I-I of Fig. 2, and

Fig. 2 is an end sectional elevation along the line II -II of Fig. 1.

as is described and claimed in my eo-pending .645, dated June 8, 1948, now Patent No. 2,593,357. The nozzle is formed by a provided with a longitudinal slot or slit-like outlet I2 from which a stream of fluid at high velocity is ejected.

the nozzle outlet for cleaning or clearing purposes, but it will be understood that the present invention is not limited to such a nozzle and it is equally applicable to nozzles having fixed walls.

I declare that what I claim is:

1. In a nozzle for the ejection of a sheet-like fluid stream and formed OFFICE contains the axis of said housing and passes through the slot, and each group of vanes on opposite sides of the mid-length of said slot being oppositely inclined, when viewed in cross section in said plane, outwardly towards the nearer end of the slot.

2. In a nozzle according to claim 1 a plurality V 4. In a nozzle formed of atl bl lar housing open at both ends for the entry of fluid and having a single continuous slot outlet in its wall parallel to its longitudinal axis, a plurality of guide vanes within the housing at spaced intervals longitudinally of the slot, each of said guide vanes extending atright angles to a plane containing the axis of said housing and passing through said slot, said guide vanes being curved and disposed divergently towards the slot and increasingly outwardly from the centre of said slot towards its two ends. 2 2
